Rolled article, and method of and apparatus for processing rolled article

Abstract

An apparatus for processing a rolled article has a rotary supporting mechanism for rotatably supporting opposite ends of a photosensitive roll, an end drawing mechanism for drawing a sheet end of the photosensitive roll to a prescribed length, a pressing mechanism for supporting opposite surfaces of the sheet end, and an applying mechanism for applying a joint tape to the sheet end supported by the pressing mechanism in a transverse direction of the photosensitive roll.

1. A rolled article comprising:
 a first flanged member mounted on a end of a roll; and  
 a second flanged member inserted in said first flanged member;  
 said first flanged member having a plurality of angularly spaced, axially extending grooves defined in an inner circumferential surface thereof, and a step of increased diameter disposed on said inner circumferential surface at an end into which said second flanged member is inserted;  
 said second flanged member having, on an outer circumferential surface thereof, a tapered tip which is progressively smaller in diameter toward a tip end thereof in a direction in which said second flanged member is inserted into said first flanged member, and a straight barrel contiguous from a larger-diameter end of said tapered tip;  
 said second flanged member having, a plurality of angularly spaced, axially extending ridges extending axially along said straight barrel in alignment with said grooves, said ridges being spaced axially from the smaller-diameter tip end of said tapered tip toward the straight barrel by a predetermined distance, and extending radially outwardly to respective radial positions corresponding to the diameter of said step of said first flanged member.
